Yr 11 Graphics Practice test with revision time given Friday 17 th Sep Sustanability
Topics to revise • What are the 6 R’s • Recycling – what materials can be recycled, what are three different types of recycling, what does recycling mean and what problems are there with recycling • Built in obsolescence – what does it mean • Symbols – mobius loop, green dot, eurpoean eco label • Refuse – why should you refuse to use/buy some products • Product life cycle – what are the 6 main stages and environmental considerations at each stage.
Revision Problems with recycling • It is difficult to separate the different materials in some products to allow them to be recycled. • It is sometimes more expensive to recycle old materials than to use new ones. • Environmentally un friendly products can be produced as a by product in the recycling process • Recycled materials are not normally as high quality as new materials.
THE RECYLCE MARK This symbol is used to encourage people to recycle wherever possible THE GREEN DOT This symbol is used on packaging in many European countries and it indicates that the manufacturer has contributed towards the cost of recycling the packaging. THE MOBIUS LOOP This is the international recycling symbol and it indicates that a product can be recycled. THE MOBIUS LOOP WITH A PERCENTAGE The percentage in the centre shows the amount of material that is recycled.
TIDYMAN SYMBOL The do not litter symbol encourages people to dispose of unwnated packaging carefully and thoughtfully. EUROPEAN ECO-LABEL This symbol is used to label and identify products that have minimal environmental impact. CARBON FOOTPRINT This symbol indicates the amount of CO 2 and other greenhouse gases emitted as part of a products manufacture, distribution, use and disposal. KITEMARK This symbol means the British Standards Institute has independantly tested a product, confirmed that the product conforms to the relevant British Standard and has issued a license to the company to use ths symbol. CE MARK This mark certifies that a product has met European Union health, safety and environmental requirements which ensure consumer safety.
Recycling – the new conversion of waste products into new materials • A recycled aluminium can saves enough energy to run a television for three hours. • If all the aluminium cans in the UK were recycled there would be 14 million fewer dustbins each year.
• Primary recycling – second hand use of items. Examples – charity shops, e bay, giving stuff away to friends/family • Secondary recycling – waste materials are recycled into different types of products. Example – a large corriflute sign could be chopped up and used as plant labels • Tertiary recycling – when products are broken down and reformulated. Example – plastic bottles can be recycled into fibres and then respun to make polyester to make a fleece • Disassembly – reprocessing materials for use in new products
Recyclable materials • • • Glass Paper and card Metals Wood Textiles Electronics Tyres Plastics Food waste
Why should you refuse to use some products? • Toxic chemicals used in the product • Made from a man made source rather than a natural source • Is the manufacturing process safe and appropriate • What about the conditions of working • Packaging and transport distances • May not be good for you
• The raw materials: how are they harvested/made? • The production process: how is the product made? • Transport and distribution: you need to consider what, how, where and the cost • Uses: what are the intended uses of the product? How will it be used by the client or customer? • Care and maintenance: what is needed, how much and is it environmentally friendly? • Disposal: the waste from manufacturing or the product itself. Ask yourself the question is it recyclable or biodegradable? Recycling: how can the product be recycled?
The story of stuff (http: //www. storyofstuff. com/)
Built in obsolescene A product has designed to become useless or outdated quite quickly. For example throw away plastic cups or a t-shirt with a slogan. Making long lasting products instead would reduce the number of products that a consumer would need to buy. Manufacturers would then make fewer products and so cut down on energy use, transport and materials.
